In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space. [1] [2] The order of the coordinates is significant, and they are sometimes identified by their position in an ordered tuple and sometimes ...
Apr 29, 2015 · $\begingroup$ @yuggib: "why do you want a metric space?" -- Any suitably generalized metric space.So we may speak of some sort of "system" at all. "your system seems to be a global coord. system; a unique map from all the space to all $\mathbb R^n$" -- That's not the intended meaning.
Mar 28, 2024 · The most common choice of coordinate system in two dimensions is the Cartesian coordinate system that we just described, where the x and y axes are perpendicular and share a common origin, as shown in Figure A1.1.2. When applicable, by convention, we usually choose the y axis to correspond to the vertical direction.
Jun 3, 2024 · coordinate system, Arrangement of reference lines or curves used to identify the location of points in space. In two dimensions, the most common system is the Cartesian (after René Descartes) system. Points are designated by their distance along a horizontal ( x) and vertical ( y) axis from a reference point, the origin, designated (0, 0).

Cartesian coordinate system with a circle of radius 2 centered at the origin marked in red. The equation of a circle is (x − a)2 + (y − b)2 = r2 where a and b are the coordinates of the center (a, b) and r is the radius. Cartesian coordinates are named for René Descartes, whose invention of them in the 17th century revolutionized ...

As the cylinder had a simple equation in cylindrical coordinates, so does the sphere in spherical coordinates: ρ = 2 ρ = 2 is the sphere of radius 2. Solution.
